Be it blown that VICTOR S Jonnson, a citizen of the United States,residin at Chicago, in the county of Cook and of lllllIlOlS, hasinvented certain newand useful Improvements in Heat-Insulated Vessels,of which the following is a speci, fication.

The invention relates to heat-insulated vessels which include an outerjacket and an inner frangible containen and said invention consistsbroadly of novel means whereby the container, if broken, may be readilyremoved and another container substituted therefor. Uther objects, also,are attained by the new construction as will hereinafter more fullyappear.

The single figure of the drawing represents a vertical sectional view ofparts of? the vemel, parts being shown in elevation.

The outer jacket 1,-is composed of a lower section 2, and an uppersection 3 which, at its lower edge, telescopes with the upper edge ofthe lower section 2 and is screwed to said lower section by screws 4ientering an anchoring nut '5.

The upper section 3 terminates below the top of the "vessel at a pointwhere it coincideswith an inner multi-part jacket 6, hav ing a shoulder7 on which an inturned lip 8 of the outer jacket it rests, the innerjacket 6 being continued upward and provided with an inturned flange 9which extends over and protects the edge of the frangible container 10.A mass oi heat-treated lac disposed between the necks of the innerjacket 6 and the container 10,'permanently unites said necks.

The space between the inner jacket 6 and the container 10, is filledwith a suitable comminuted heat insulation 11, and the outer jacket 1and the inner jacket 6 are separated to provide a non 'heat conductingair space 12 which supplements the action of the heat insulation 11.

The neck 13 of the inner jacket 6 is screwthreaded to receive ascrew-threaded drink in cup 1dof ordinary character.

he bail 15 is connected to the vessel by ears 16 secured to the uppersection 3 of the outer j acket,the object of this arrangement being toavoid the removal of the bail and its ears when the inner jacket and afractured frangible container are removed.

When a new container is to be substituted tate 19th. fierial Kilo.

per section is set aside. The old filler, in-

eluding its container .is then taken out and a new filler including aninner acket 6, a frail ible container 10, and insulating materia 11, isinserted in its place. The section 3 is then replaced and made fast bythe screws. d.

The-inner jacket 8 has a joint l8'uniting two of its sections 19, 20,and the section 20'has a bottom-2i provided with cavities 2% fittingknobs %3 in the bottom 24 of the section 2 oi the outer jacket,thesedevices insuring a minimum area of contact between the two jackets,and the filler as a whole, being prevented from turning in the outerjacket by said cavities 22 and knobs 23.

The device provided with a heat-insulated stopper which is not hereinclaimed.

Having thus described my invention, ll claim:

l. A heat-insulated vessel including a removable outer jacket and aunitary filler, said filler including a frangible container, aheat-insulator surrounding said container, and a jacket enveloping saidheat-insulator, said filler jacket being spaced from said outer jacket.

2. A heat-insulated vessel including an outer jacket and a removableunitary filler, said tiller including trangiblecontainer, a

tilt

heat-insulator surrounding said container,

and a jacket enveloping said heatinsulator,

said filler jacket being spaced from-said outer jacket. 4

3. A heat insulated vessel -including an outer jacket and a unitaryfiller disposed within said outer jacket and interlocked with said outerjacket at its base to prevent said filler from rotating relatively tosaid jacket. i

ii. A heat-insulated vessel including an outer jacket and a removableinnerjacket, said outer jacket having a knob in its base portion andsaid inner jacket having a cavity into which said lmob extends.

5. A heat-insulated vessel including a multi-part' outer jacket and aunitaryremovable filler provided with a frangible container and a neckportion constitutin a separable continuation of said outer jac st andsecured to the wall of said container.

6. A heat-insulated vessel including an ice outer jacket, a removableinner jacket ex-' tending above the outer jacket, and a frangiblecontainer heat-insulated from said inner jacket and held at its upperend by the upperend of said inner jacket.

7; A heat-insulated vessel of the nonvacuum type including a multi-partouter jacket and a bail for said outer jacket, and including also a.removable composite filler extending above said outer jacket andprovided with a heat-insulated, frangible container.

8. A heat-insulated vessel including, a unitary filler comprising aninner frangible container, heat-insulating material surrounding saidcontainer, and a jacket surrounding said heat-insulating material, andincluding also an outer jacket terminating at and extending over ashoulder of the jacket of said filler.

9. A heat-insulated vessel including a permanent portion, and a bailfixed to said permanent portion, and including also a eat-insulatedremovable frangible container, extending above said permanentportion.

10. A heat-insulated vessel including a multiart outer jacket and aunitary removabe filler, said filler being held between an inturnedportion of said outer jacket and the bottom of said jacket when thesesections of said outer jacket are united. a

11. A heat-insulated vessel including a multi-part outer jacket andaunitary removable filler, said filler being held between an inturnedportion of said outer jacket and the bottom of said jacket when thesesections of said outer jacket are united, and

interlocked with the lower section of said outer jacket to preventrotation thereof in said outer jacket.

12. A heat-insulated receptacle of the non-vacuum type: including amulti-part outer jacket and a unitary removable filler, saidfiller'having an inner frangible container and a jacket of non-frangiblematerial spaced away from said container around its body portion, thespace between said container, and jacket being filled with heat andshock insulating material, and said filler being spaced away from theouter jacket.

13. As an article of manufacture, a unitar-y'heat-insulated filler ofthe non-vacuum type comprising a strong frangible con t'ainer, andanouter jacket spaced from the container and having near its upper end ashoulder and at its lower end a depression, the space between saidcontainer and said jacket beingfilled with heat-insulating andshock-absorbing material. I

14:. A heat-insulated vessel of the nonvacuum type, having an outermulti-part protective jacket and a unitary removable filler, said fillerincluding a frangible container and a jacket of non-frangible materialspaced from said container, the space between said container and saidjacket be-- ing filled with comminuted heat-insulatingmaterial, and saidfiller jacket having a depression near its top coinciding with the outerprotective jacket andan interlock at its bottom ot prevent said fillerfrom rotating within said protective jacket.

In testimony whereof I aflix my signature.

VICTOR s. JOHNSON.
